IMPROVED DISCHARGER FOB GENTRIFUGAL MACHINES.

TO ALL WHOM IT MAYCONGERN Be it known that I, HELEM MERRILL, of Brooklyn, in the county of Kings, and State of New York, have invented a certain new and useful machine, which I term a Discharger for Centrifugal Machines; and I ,do hereby declare that the'following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making a part of this specification, and to the letters of reference marked thereon.

\Vhen a centrifugal machine has performed its work on a charge of sugar or other material, it has hitherto been necessary to stop its motion in order to empty it by hand. The time involved in discharging is usually much greater than that required for operating upon the charges,and the machines are more injured by the violence to which they are generally subjected in hastily shovelling the sugar from the interior of the sieve, than by the natural operation of the machine when in motion.

To avoid this objectionable loss of time and rough handling, my invention consists of a receptacle which may be placed in the interior of the machine, and supported by the stationary outer casepso that it also remains stationary while the rotation of the sieve around it causes the charge to he scraped off by projecting edges, and deposited within the receiver, with which it may be lifted from the machine without requiring the stoppage of the latter. The receiver is made in sections that are hung on pivots or hinges, so that their outer edges may be pressed upon the revolving sugar and sieve in an angular direction opposite to that of the motion, in such a manner that the sugar is'scraped fromthe sieve and carried within the receiver, where it remains until removed from the machine. The sections or scrapers are connected to a handle or lever, by which they may all be pressed '1 simultaneously upon the inner surface of the revolving sieve; and they should be so hung that they will yield automatically in the event of any undue strain caused, for instance, by the catching of an edge or corner against a torn portion of the sieve. By using three sections or scrapers at uniform distances apart, the action of the strain upon the sieve will beuniformly distributed.

To enable others skilled in the arts to which it apportains to make and use my invention, I will proceed to describe its construction and operation with reference to the drawing.

Figure 1- is a sectional elevation of acentrifugal machine, showing the application of a discharger of my invention in position for use; and i Figure 2 is a plan of the same.

The sections a are hung onthe arms of shafts b that are carried on a triangular frame, a, resting on bolts or between brackets on the stationary part of the frame. The red lines show the position of the'sections when they have been expanded outwards against the sieve. They may be faced with leather, and the shafts on which they are hung may be turned together or separately in any convenient manner. The discharger is placed in the machine, as drawn in black lines, without interfering with its motion; and when the sections are expanded and pressed against the sugar, it -is scraped from the sieve and carried within the sections, which are then again retracted and lifted from the machine. The sections are all lifted together with the. frame, and each section may be separately unhooked from the arms on which it is suspended.

Having thus described the manner in which I prefer to carry my invention into efi'ect, I hereby state that Ldo not propose to confine myself to the details illustrated in the drawings, Whichmay be supplied with guards and guides, and must necessarily be varied in adaptation to the difierent patterns of centrifugal machines in use When the power is applied beneath the machine, I prefer to connect the sections and lift and deposit them together; but when the power is applied above, the sections may be separated, so that they work on each side or between the frames; and in some cases the receiver-may be made in the form of a single-cylindrical vessel, with scrapers projecting through suitable slots and bearing upon the charge and surface of the sieve in an angular direction opposed to the motion in a similar manner to that which I have described.

I claim as my invention-- The stationary and removable scrapers and receptacles by which a centrifugal machine may be discharged when in motion, substantially as described.

HELEM MERRILL.
